0.5= 2/x

Solution

0.5 = \frac{2}{x}

x = 4

Solution steps

0.5 = \frac{2}{x}

Multiply both sides by

x

0.5 x = 2

Divide both sides by

0.5

x = 4

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 4

(x + 125) (\frac{150}{x + 25}) = 150

\frac{2}{3 x + 4} = \frac{1}{2 x - 1}

0.0177 = \frac{lo g _{10} ( 0.29 )}{( a - x )}

\frac{5}{x} - \frac{1}{( x + 2 )} = 1

52 = \frac{n}{2 [ 2 ( - 8 ) + ( n - 1 ) ( - 2 ) ]}
